Description

The adjustable upsetter of a kind of single direction rotation thimble and method of work

Technical field

The present invention relates to upsetter and method of work thereof.

Background technology

Traditional upsetter, punch die and die all are fixed on corresponding pedestal, the upsetting efficiency of this structure is low, charging and discharging all cumbersome.

In order to enhance productivity, the transposition that develops into afterwards the upsetting inter process be by drift move back and forth realize.This upsetter, complex structure, be difficult for realizing the high speed upsetting especially.In order to solve the problem of high speed upsetting, the patent No. is in the patent of invention of ZL87105260.1, a kind of multistation die-revolving high-speed upsetter is disclosed, this invention provides the die more than at least three on the revolution die socket, on slide block, will fill and the same number of punch die corresponding with the die of die socket; The die of its feed entrance point is same die with the die of shaping position for the first time, and the die of the die of discharging position and the last shaping position of workpiece is same die.By cutting material level, put the clamping blank before feed entrance point, punch die need be greater than charge length to the stroke of the motion of the direction away from die, then blank is put and is clamped to feed entrance point by cutting material level, then by the punch die of moulding for the first time, blank is poured to upsetting moulding for the first time in die.When workpiece ejected, punch die need reset to the direction away from die and its movement travel need be greater than the length of workpiece.This upsetter, all for moulding, charging and discharging all need to take the time of workpiece upsetting moulding on the one hand, have affected operating efficiency due to the die in feed entrance point and discharging position; On the other hand, for enough chargings being arranged and going out material space, the essential length that surpasses blank or workpiece of the stroke of punch die, this not only greatly reduces the operating rate of upsetter, increase the stroke wearing and tearing of large slide block and the motion power consumption of machine, and greatly increased volume and the cost of upsetter equipment.

In order to solve the problems of the technologies described above, a kind of multi-stage female die returning jolting machine is disclosed in application number is 201020124750.1 patent documentation, specifically disclosing multi-stage female die returning jolting machine comprises large slide block, is fixed on the die assembly on large slide block, the large slider-actuated mechanism that makes that large slide block moves back and forth, the die assembly, cut feed collet material mechanism, the workpiece ejecting mechanism, make die rotate the die indexing means of desired location, the die positioner that die is stopped at desired location, material jacking mechanism; The die assembly only comprises the die socket of support rotation relatively, along die, circumferentially is evenly distributed on the die more than two or two in die socket; Many two than the number of punch die of the numbers of die, comprise the die of die, discharging position of feed entrance point and shaping position and punch die die one to one; Die position in the corresponding charging of punch die one side is provided with the blank propulsive mechanism in the die that blank is advanced to feed entrance point, on the large slide block of punch die one side, is provided with empty avoiding and cuts the empty avoiding space of feed collet material mechanism, blank propulsive mechanism, the corresponding discharging position discharging clearance position when being provided with workpiece and being ejected.

The upsetter of said structure, due to the number of die than the number of punch die many two, therefore, charging die and discharging die and punch die dislocation, like this, the movement travel of punch die can be less than the length of blank, but and also charging when upsetting, thereby solved the technical problem of traditional upsetter.

But in above-mentioned disclosed upsetter, the die socket rotation, thimble is followed rotation together, one end of thimble contacts with the spacing abutment of thimble, and the spacing abutment of thimble maintains static, and therefore, between thimble and the spacing abutment of thimble, can produce larger frictional force, be easy to make the thimble distortion or fracture, thereby causing this upsetter to work.

Summary of the invention

For solving the problems of the technologies described above, the invention provides the adjustable upsetter of a kind of single direction rotation thimble and method of work thereof.

The technical scheme that solves the problems of the technologies described above is: the adjustable upsetter of single direction rotation thimble, comprise die assembly, die assembly, die rotating mechanism, material jacking mechanism and drive the die assembly driving mechanism that die assembly moves, described die assembly comprises the die holder, is located at the die socket in the die holder and is located at the die in die socket; Described die rotating mechanism drives the die socket rotation; Described material jacking mechanism comprises thimble, push rod, keep out seat, knock-pin and drive the liftout drive unit of knock-pin to the motion of die direction, in die socket, corresponding to each die, be provided with described thimble, one end of push rod extend in die socket, and an end of push rod contacts with thimble, the described seat of keeping out is located in the die holder, knock-pin is corresponding to a wherein die setting, when the needs liftout, knock-pin push rod contact overhead push rod, at push rod with keep out between seat and be provided with the rolling contact device.

The method of work of the adjustable upsetter of single direction rotation thimble is:

(1) when blank was pushed in die, thimble and push rod together retreated, and by keeping out the going-back position of seat to thimble, were undertaken spacing and withstood push rod.

(2) then, the die assembly driving mechanism drives the die assembly motion, and die assembly carries out upsetting to blank.

(3) after completing a upsetting, the rotation of die rotating mechanism driving die socket, die socket drives die and thimble together rotates, and die socket is in rotary course, and the rolling contact device is rolling friction with keeping out seat.

(4) after the die socket rotation completes, the liftout drive unit drives pre-knock-pin and knock-pin moves to the die direction, pre-knock-pin promotes the push rod corresponding with pre-knock-pin and thimble motion, and outwards moved by corresponding workpiece in the thimble promotion die corresponding with pre-knock-pin, simultaneously, knock-pin promotes corresponding push rod and the thimble motion of die of discharging, and by thimble, is ejected corresponding workpiece in the die of discharging.

(5) repeat above-mentioned steps (1) to step (4) and carry out upsetting next time.

Said structure and method of work, owing to being provided with the rolling contact device, when die socket rotates, rolling contact device and keeping out between seat as rolling friction, and between thimble and rolling contact device, also be provided with push rod, thimble is not subject to direct distortion power, therefore, thimble is not easy distortion, also is not easy to fracture, the functional reliability of upsetter is good, and the life-span is long.
